Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a support pole for a street tree or a tree planted in a park or the like.

(Conventional examples, configurations, and their problems) Traditionally, trees such as roadside trees have been supported with wooden pillars in order to protect them from growing. Not only cannot it withstand long-term use, but it also has the disadvantage that assembly work on site is time-consuming.

For this reason, tree supports made of metal pipes have been devised, for example, as described in Japanese Utility Model Publication No. 54-17646.

However, this support consists of a T-shaped middle support and a pair of L-shaped bent side supports, with the bent horizontal part of the upper end of the side support being attached to both ends of the upper horizontal rod part of the middle support. Because these side columns rotate independently relative to the middle column, it is difficult to adjust and secure the desired root gap between the columns. Become.

In addition, since these supports are bent in a T-shape or L-shape, there are problems such as the bending part hinders handling during transportation and work, and requires a large storage space. It was hot.

(Purpose of the invention) The present invention was made in view of the above problems, and it is an object of the present invention to provide a tree support that has a simple shape, is easy to handle, can be assembled smoothly, and can secure the desired root opening. It is something.

(Structure of the Invention) In order to achieve the above object, the tree support of the present invention includes a horizontal support rod 1 whose both ends are bent upward and inclined 2, 2;
The horizontal support rod 1 consists of a pair of left and right side supports 5, 5 whose upper ends can be fixed to the horizontal support rod 1, and a central support 8 whose upper end is locked to the center of the horizontal support rod 1. By fixing the upper ends of the side struts 5, 5 to the bent inclined portions 2, 2 at both ends, and locking the upper end of the central strut 8 to the center of the horizontal support rod 1, the desired root opening and inclination can be achieved. It is designed so that it can provide a high degree of accuracy.

(Explanation of Embodiments) The embodiments of the present invention will be explained with reference to the drawings.
is a horizontal support rod made of metal, whose both sides are bent obliquely upward, and a threaded portion 3 is formed on the bent inclined portions 2, 2, and an arc-shaped screw portion is formed at the base end of the bent inclined portion 2. A curved circular washer 4 is fixed by welding or the like.

Reference numerals 5 and 5 denote a pair of left and right side supports made of straight metal pipes or rods, whose upper ends pass through mounting holes 6 between both sides through which the horizontal support rod 1 can be inserted;
A rectangular bottom plate 7 is integrally fixed to the lower end surface.

Reference numeral 8 denotes a metal center column having the same size and shape as the side column 5, and has a locking hook 9 integrally attached to one side of its upper end, and further has a rectangular bottom plate 7 fixed to its lower end surface. .

Reference numeral 10 denotes a circular washer for clamping, which has a through hole 11 in the center through which the bent inclined parts 2, 2 of the horizontal support rod 1 can be inserted, and the circular washer is fixed to the bent inclined part 2 of the horizontal support rod 1. 4 to sandwich the upper end of the side support 5 from both sides.

12 is a threaded portion 3 of the bent inclined portion 2 of the horizontal support rod 1
This is a fixing nut that is screwed onto the

Reference numeral 13 denotes a cap fitted onto the upper end of each support column 5, 5, 8.

The tree support constructed in this way is arranged on the tree a to be supported in the following manner.

First, the upper end mounting holes 6 of the side struts 5, 5 are inserted into the bent inclined parts 2, 2 of the horizontal support rod 1, and the inner surface of the upper end is brought into contact with the fixed circular washer 4, and then the clamping washer 10 is inserted into the bent inclined part 2 and brought into contact with the outer surface of the upper end of the side strut 5, and the nut 12 is screwed into the screw part 3 of the bent inclined part 2. 2, 2 with side struts 5, 5
with the same inclination and toward the lower end.
Fix the distance so that it gradually increases.

Next, the horizontal support rod 1 is placed along the appropriate height of the tree a, and the lower ends of the side supports 5, 5 are placed in a recess (not shown) drilled in the ground around the tree a. The upper end locking hook 9 of the central column 8 is locked to the center of the horizontal support rod 1, and the lower end of the central column 8 is supported in a recess in the ground. At this time, by adjusting the inclination degree and root opening of the central column 8 and the side columns 5, 5, and then backfilling the depression with soil, the bottom plate 7 fixed to the lower ends of the columns 5, 5, 8 will be removed. It exhibits a large resistance against pulling force, etc., and firmly supports the tree a.

(Effects of the invention) As described above, according to the tree support of the present invention, the horizontal support rod 1 has both ends bent upward and has inclined parts 2, 2.
and a pair of left and right side supports 5, 5 whose upper ends can be fixed to the bent inclined parts 2, 2 of the horizontal support rod 1.
and a central support 8 whose upper end is locked to the center of the horizontal support rod 1, so that side supports 5, 5 are attached to both ends of the horizontal support rod 1 with bent inclined portions 2. . The root opening and inclination can be obtained, and these supports 5 and 8 can be easily assembled.

In addition, the horizontal support rod 1, the side columns 5 and the central column 8
Because they are all straight, they are not only easy to manufacture and can be provided at low cost, but also easy to transport and handle in bundles, easy to store, and easy to assemble. .
